Abstract

A monitor calibration method for determining the black point of a monitor display, wherein a solid black display area and a gray display area are displayed on a monitor screen in the form of stripes, for example, so that each display area is sandwiched by the other type of display area. Then, while the brightness of the gray display area is gradually changed, the user signals OK using a mouse device at the point in time that the viewer determines a difference between the two display areas. The input value of the gray display area at that time is fixed and saved as the black point. By arranging the display areas in alternating stripes, even a subtle difference in the two display areas is visually striking. Hence, a very accurate black point can be determined.
